If you know that Indy and Fort Wayne are actually 120 miles apart, how far apart would Indy and Kokomo be in real life? Express your answer rounded to the nearest tenth of

Answers

Answer: 60 miles

Step-by-step explanation:

On a map, Indy and Fort Wayne are 19 centimeter apart while Kokomo and Indy are 9.5 cm apart on the map.

In real life, Indy and Fort Wayne are actually 120 miles apart, the distance between Indy and Kokomo in real life would then be:

= 9.5 × 120/19

= 120/2

= 60 miles

Indy and Kokomo are 60 miles apart in real life.

The figure below shows a right triangle:

What is r ÷ p equal to? (6 points)

Group of answer choices

A. sin y°

B. sin x°

C. tan y°

D. tan x°

Answers

Answer:

tan y°

Step-by-step explanation:

by using the Sine Rule (See attached), we can form the equation:

[tex]\frac{r}{sin (y)} = \frac{p}{sin (x)}[/tex]

rearranging this, we get:

[tex]\frac{r}{p} =\frac{sin(y)}{sin(x)}[/tex]   ---------------------eq 1

Recall that all internal angles of a triangle must sum to 180°. we observe that we have a right triangle where one of the angles is 90°. It then follows that the sum of the other two angles must sum to 90°

i.e x + y = 90°

with a little rearranging, we get

x = (90° - y)

Substituting this into eq 1 above, we get:

[tex]\frac{r}{p} =\frac{sin(y)}{sin(90- y)}[/tex]  ---------eq 2

recall that from the trigonometric co-function identities,

sin (90°- y) = cos y

substituting this into eq 2 gives :

[tex]\frac{r}{p} =\frac{sin(y)}{cos(y)} = tan(y)[/tex]   (answer)

Would it be better to have a loan with 5% interest payback in 2 years, or a loan with 2% interest paid back in five years? Explain. Show work to justify your answer.

Answers

Step-by-step explanation:

If the interest on the loan is simple interest. Both the situation will have equal amount of interest ( 5*2 =10% of total amount). Therefore, it would be better to pay back with 2% interest paid back in five years. However, if the interest is compounded annually, 5% in 2 years will have lesser interest than 2% in 5 years. Hence, Former option would be better.

There of the ABCD are given. fine the coordinates of point D. A(3, 6) B(6,3) D(x, y)

Answers

Answer:

A. (3,2) . I recommend using desmos to find the coordinates

9514 1404 393

Answer:

  A.  (3, 2)

Step-by-step explanation:

The midpoints of the diagonals are the same point, so you have ...

  X = (A +C)/2 = (B +D)/2

  A +C = B +D . . . . . . . multiply by 2

  A +C -B = D . . . . . . . subtract B

The coordinates of D are ...

  D = (3, 6) +(6, 3) -(6, 7) = (3+6-6, 6+3-7)

  D = (3, 2)

A paperweight in the shape of a rectangular prism is shown: A right rectangular prism is shown with length 10 cm, width 4 cm, and height 4 cm. If a cross section of the paperweight is cut diagonal to the base, which shape describes the cross section?

Answers

Answer:

Square

Step-by-step explanation:

CHECK THE ATTACHMENT FOR THE FIQURE OF THE QUESTION

✓We were given the dimension of the rectangular prism as 10cm × 4cm × 4cm,

✓The cross section of the paperweight can be cut into half to it's base. Then the new dimension will be 4cm × 4cm which is a quadrilateral.

✓ Then width= 4cm, and height=4 cm are of the same values, hence the shape it forms is a SQUARE. and also the their angles is 90° each.
